What are the limits to organ growth? Simple exponentional doubling
will get you there rather fast, even with a 24 hour doubling time.
What are we talking about here, one trillion cells or so? That's
40 days. This won't help an accident victim which needs a replacement
*now*, but for your typical degenerative diseases there's ample
warning time.
